[PATCH 5/6] ARM: convert PCI defines to variables
From: Rob Herring
Date: Wed Jun 29 2011 - 12:48:16 EST
From: Rob Herring <rob.herring@xxxxxxxxxxx>
Convert PCIBIOS_MIN_IO and PCIBIOS_MIN_MEM to variables to allow
multi-platform builds. This also removes the requirement for a platform to
have a mach/hardware.h.
Signed-off-by: Rob Herring <rob.herring@xxxxxxxxxxx>
